This study aimed to evaluate the suitability of two bioaerosol generation systems(dry and wet generation) for the aerosolization of microorganisms isolated from the International Space Station, and to calibrate the produced bioaerosols to fulfill the requirements of computational fluid dynamics model(CFD) validation. Concentration, stability, size distribution, agglomeration of generated bioaerosol and deposition of bioaerosols were analyzed. In addition, the dispersion of non-viable particles in the air was studied.Experiments proved that wet generation from microbial suspensions could be used for the production of well-calibrated and stabile bioaerosols for model validation. For the simulation of the natural release of fungal spores, a dry generation method should be used. This study showed that the used CFD model simulated the spread of non-viable particles fairly well. The mathematical deposition model by Lai and Nazaroff could be used to estimate the deposition velocities of bioaerosols on surfaces, although it somewhat underestimated the measured deposition velocities. 相似文献

历史上的趋势用铁路进行运输的质量是无容置疑的,甚至于其竞争的对手也都承认:铁路节省空间的占用,还节省是因为耗能少,因为普遍使用电能因此少污染,很少产生温室效应的气体. 相似文献

In the context of climate change, this study evaluates the impact on the long-shore and cross-shore sediment transport (LST and CST) along the Catalan coast (NW Mediterranean Sea) derived from climate projections obtained from five combinations of regional and global circulation models (RCMs and GCMs). Special emphasis is given to how inter-model variability translates from wave projections to wave-driven coastal impacts, which is still poorly known. Results show that the uncertainty is in general larger, especially for LST, for which the discrepancies among regional models are more relevant than those associated with the forcing wave parameters. Such increase in the uncertainty can be explained by the nonlinear processes involved, and the role of the forcing wave parameters having sometimes competing effects (e.g. wave height vs. wave direction). This illustrates that the performance of each RCM–GCM can vary from forcing to impact parameters; hence, the suitability of a particular RCM–GCM to evaluate a certain impact should be assessed based on its ability to properly simulate such impact. In this regard, LST and CST rates computed using empirical formulae that integrate several wave climate parameters, as in this study, can be used as a non-computationally expensive tool to assess the suitability of a given RCM–GCM to project changes in coastal dynamics. 相似文献

SUMMARY A participatory research programme was conducted in the groundnut basin of Senegal, where there was a need to intensify the local farming systems. The research yielded a set of technical references and profitable innovations, which were introduced through specific development actions. The technology transfer aims at the establishment of sustainable farming systems and takes into account the climatic risks and innovation costs. Identification of research themes and implementation of results was based on various analyses: climatic analysis at regional level (establishment of climatic zones) and identification of constraints at farm level. Farmers' interests and the research results were combined to define suitable interventions for each surveyed farm, with the aim of increasing farm income and restoring soil fertility. The research also yielded elements for formulating an appropriate and realistic agricultural policy for the region. Clearly, the development of livestock farming activities is essential in bringing new economic life into the region and increasing the sustainability of farming systems in erratic climatic conditions. 相似文献
